[. . . ] Sonar Views
Sonar View presents a historical log of the stored sonar returns. The most recent sonar returns are charted on the right side of the window; as new information is received, the older information is moved across the display. A scale with Upper and Lower Depth Range readouts appears along the right edge of the Sonar View. indicates the distance from the surface of the water Additional purchase required.

How Sonar Works
Sonar technology is based on sound waves. The MatrixTM Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as calibrate digital depth directly below the transducer. Your Matrix unit sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object. Note: When operating in Simulator state with a transducer connected, Menu setting changes are saved to memory. If a transducer is not connected, changes will not be saved and Menu settings will revert to factory defaults every few minutes.
WARNING: Disassembly and repair of this electronic unit should only be performed by authorized service personnel.

Handling and/or opening this unit may result in exposure to lead, in the form of solder. WARNING: This product contains lead, a chemical known to the state of California to cause cancer, birth defects and other reproductive harm.

Surface Clutter Adjusts the filter that removes surface clutter noise caused by algae and aeration. (Low=1, High=10, Default=Low) Adjusts the sonar Noise Filter to limit interference from sources such as your boat engine, turbulence, or other sonar devices for best display performance. (Off, Low, Medium, High, Default=Low)
Note: The Off setting removes all filtering; Low, Medium and High settings add progressive filtering of the sonar returns. In some deep water situations, the High setting may actually hinder your unit's ability to find the bottom.
Noise Filter
Water Type
Configures unit for type of water conditions. (Salt, Fresh, Default=Fresh)
Note: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this. Also, make sure that the Water Type is set accurately, especially in salt water, as this can affect the accuracy of deep water depth readings.
